HEEL-CALK.

Application filed May 17, 1916. Serial No. 98,036.

To all whom it may concern:

Be it known that I, OSCAR B. HANSON, a citizen of the United States, residing at Hartford, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Heel- (lalks, of which the following is a specification.

The object of this invention is to provide a detachable heel calk for horseshoes such that said calk may be easily and quickly replaced without the necessity of removal of.

the shoe or subjecting either the shoe or the calk to heat to accomplish the attachment.

In carrying out the invention the aim has been to produce a simple article of manufacture enabling the replacement above referred to at a minimum expense and without resorting to a blacksmith to perform the work.

For a full understanding of the present invention, reference is to be had to the following description and the accompanying drawing, in which:

Figure 1 is a perspective View of a shoe having this invention applied thereto.

Fig. 2 is a sectional view of an extremity of the shoe showing more clearly the manner in which the calk is secured in place.

Fig. 3 is a perspective view of a calk member alone.

Fig. 4 is a fragmentary view of the shoe extremity to which the calk is applied.

Fig. 5 is a slight modification of'the invention.

Fig. 6 is a detail fragmentary view of the shoe terminal adapted forthe modification shown in Fig. 5.

Throughout the following detail description, and on the several figures of the drawing, similar parts are referred to by like reference characters.

Referring to the drawing, the numeral 1 indicates the body of a heel calk which con stitutes the subject matter of this invention, said body being of wedge shape formation or tapered as usual in order to provide a sharp surface engaging element. The body of the calk is formed with an aperture 2 at its upper portion and directly adjacent said aperture on the face of the calk is formed a bendable flange 3. One of these calks is attached toeach extremity of the horseshoe 4, said extremities for this purpose being reduced so as to receive the calk thereon in the manner most clearly shown in Fig. 2. The reduced extremity 5 is rectangular in formation and adjacent such extremity the shoe is formed with a flange 6 about which the projecting member 3 is designed to be bent for the purpose of holding the calk in position upon the shoe extremity.

As will be observed in Fig. 5, each end of the shoe may be apertured to receive a pin 7 which will effectively lock the calk against accidental displacement. Furthermore the flange 6 in this modified form is notched and the projecting element 3 of the calk is received in said notch when attaching the calk in place.

The shoe 4 may be provided with any desired form of toe calk such as indicated at 8 which, not forming the subject matter of this invention, is not specifically described.

Having thus described my invention, what I claim as new is:

1. In combination, a horseshoe having a notched flange projecting downwardly therefrom at each heel extremity, a calk adapted to bedeta'chably connected to said extremity and comprising an apertured body through which a heel extremity is received, and a bendable projection extending inwardly from the face of said body be,- neath the aperture aforesaid and adapted to be bent upwardly into the notch of the heel flange and about said flange to interlock the calk on said shoe.

2. In combination, a horseshoe having reduced heel extremities, a flange projecting therefrom at each heel extremity, a calk adapted to be detachably connected to each extremity and comprising an apertured body in which an extremity is received, a bendable projection extending from said extremity and engageable about the flange to interlock the calk on said-shoe, the reduced Specification of'Letters Patent. Patented Feb, 13, 1917. i

portion aforesaid being apertured, and a OSCAR B. HANSON.
